1998 MITSUBISHI MONTERO maintenance schedule

Engine pre-oiling can be done using pressure oiler (if
available). Connect pressure oiler to cylinder block oil passage
such as oil pressure sending unit. Operate pressure oiler long enough
to ensure correct amount of oil has filled crankcase. Check oil level
while pre-oiling.
If pressure oiler is not available, disconnect ignition
system. Remove oil pressure sending unit and replace with oil pressure
test gauge. Using starter motor, rotate engine starter until gauge
shows normal oil pressure for several seconds. DO NOT crank engine
for more than 30 seconds to avoid starter motor damage.
Ensure oil pressure has reached the most distant point from
the oil pump. Reinstall oil pressure sending unit. Reconnect ignition
system.
INITIAL START-UP
Start the engine and operate engine at low speed while
checking for coolant, fuel and oil leaks. Stop engine. Recheck coolant
and oil level. Adjust if necessary.
CAMSHAFT
Break-in procedure is required when a new or reground
camshaft has been installed. Operate and maintain engine speed between
1500-2500 RPM for approximately 30 minutes. Procedure may vary due to
manufacturers recommendations.
PISTON RINGS
Piston rings require a break-in procedure to ensure seating
of rings to cylinder walls. Serious damage may occur to rings if
correct procedures are not followed.
Extremely high piston ring temperatures are produced obtained
during break-in process. If rings are exposed to excessively high RPM
or high cylinder pressures, ring damage can occur. Follow piston ring
manufacturer's recommended break-in procedure.
FINAL ADJUSTMENTS
Check or adjust ignition timing and dwell (if applicable).
Adjust valves (if necessary). Adjust carburetion or injection idle
speed and mixture. Retighten cylinder heads (if required). If
cylinder head or block is aluminum, retighten bolts when engine is
cold. Follow the engine manufacturer's recommended break-in procedure
and maintenance schedule for new engines.
NOTE: Some manufacturer's require that head bolts be retightened
after specified amount of operation. This must be done to
prevent head gasket failure.

MAINTENANCE SERVICE INFORMATION
SEVERE & NORMAL SERVICE DEFINITIONS
Service is recommended at mileage intervals based on vehicle
operation. Service schedules are based on the following primary
operating conditions.
Normal Service
* Driven More Than 10 Miles Daily
* No Operating Conditions From Severe Service Schedule
Severe Service (Unique Driving Conditions)
NOTE: Use the Severe Service schedule if the vehicle to be serviced
is operated under ANY (one or more) of these conditions:
* Driving In Dusty Conditions
* Towing A Trailer, Police, Taxi, Or Commercial Type Operation
* Extensive Idling, Driving In Stop And Go Traffic
* Short-Trip Operation At Freezing Temperatures
(Engine Not Thoroughly Warmed Up)
* Driving In Sandy Areas
* Driving In Salty Areas
* More Than 50% Operation In Heavy City Traffic Or At Sustained
High Speeds During Hot Weather Above 90
\bF (32\bC)
* Driving On Off-Road
CAMSHAFT TIMING BELT
Replace the camshaft timing belt every 60,000 miles. It is
recommended that the timing belt be inspected every 30,000 miles after
replacement.
CAUTION: Failure to replace a faulty camshaft timing belt may result
in serious engine damage.
The condition of camshaft drive belts should always be
checked on vehicles which have more than 50,000 miles. Although some
manufacturers do not recommend belt replacement at a specified
mileage, others require it at 60,000-100,000 miles. A camshaft drive
belt failure may cause extensive damage to internal engine components
on most engines, although some designs do not allow piston-to-valve
contact. These designs are often called "Free Wheeling".
Many manufacturers changed their maintenance and warranty

cautions and warnings have been observed to prevent vehicle damage or
personal injury. See CAUTIONS & WARNINGS in MAINTENANCE INFORMATION

Introduction
The frequency of scheduled inspection and maintenance
services in this article are based on "normal" vehicle usage. They DO
NOT take into account the following "severe" conditions:
* Driving In Dusty Conditions
* Trailer Towing, Police, Taxi, commercial Type Operation
* Extensive Idling, Driving In Stop-And-Go Traffic
* Short Trip Operation At Freezing Temperatures (Engine Not
Thoroughly Warmed Up)
* Driving In Sandy Areas
* Driving In Salty Areas
* More Than 50% Operation In Heavy City Traffic Or At Sustained
High Speeds During Hot Weather Above 90
F (32C)
* Driving On Off-Road
If any of these severe conditions exist, the "normal" service
schedule frequency for some service items is inadequate and must be
supplemented. See the following section for specific details,
SEVERE SERVICE CONDITIONS/ACTIONS .
SEVERE SERVICE CONDITIONS/ACTIONS
The following table identifies eight "severe" conditions that
cause faster-than-normal wear. Each condition lists affected service
item(s) and their revised (more frequent) service interval.
If any severe condition(s) is applicable, its revised service\
interval(s) supersede those found in the "normal" schedules. Depending\
on the specific mileage/time, the revised interval(s) may overlap a
normal schedule (in which case they can be done together). If not, it
must be performed outside of the normal schedule.
